SHE might have opted for a bit of colour on Monday, but Princess Beatrice was back to her signature dark hues last night during a date night with her beau.

The 25-year-old - who rubbed shoulders with the fashion and film elite at the Creative London party on Monday - headed out to famous London eatery Nobu with her boyfriend Dave Clark, and looked uber chic in an all-black ensemble.

Showing off her shapely legs, the young royal opted for a skater-style skirt, which she teamed with a loose-fitting black shirt and cropped leather jacket.

But adding a splash of colour, Beatrice finished off her look with a bright green shopper bag, which she toted in her left hand.

Oozing confidence as she left the celebrity haunt, the flame-haired princess appeared in great spirits as she made her way to an awaiting vehicle with her businessman boyfriend.

And it seems as though she had every right to be in a good mood, after dining alongside childhood hero Ronan Keating.

Having grown up when Boyzone were at their most famous, it wouldn't be surprising for the daughter of the Duchess of York to be somewhat starstruck by her fellow diner.

Ronan was later spotted exiting the venue and jumping into a taxi with his gorgeous girlfriend Storm Uechtritz and another pal.

The trio looked in great spirits as they smiled for awaiting photographers outside the restaurant, clearly having enjoyed their meal inside.

Beatrice has had a busy week already after making an appearance at the Creative London party on Monday night.

The star looked gorgeous as she stepped away from her usual palette and opted for a floral skirt and a silk blouse, showing off her stunning figure.

The event was hosted by the British Fashion Council, the British Academy of Film and Television and the British Recorded Music Industry and Beatrice managed to enjoy a chat with Net-a-Porter founder Natalie Massenet as well as Marchese co-designer Georgina Chapman and her husband Harvey Weinstein.
